item_ID_list.csv

This file contains the following columns

* unique_id: A unique ID number that is used in production datasets. This is unique for each species
 		(or lowest taxonomic group where data is available). 
* species: Common or latin name for each "species" each unique ID has a corresponding species entry. 
* item_code: The code used for terrestrial species/food items in FAOSTAT (therefore only exists for terrestrial production). 
* Item: The item name that matches the item code (therefore also only terrestrial). 
* nut_ID: A unique ID for nutritional composition. Terrestrial animal production for example is split into multiple
		categories due to varying nutritional content (e.g. meat vs fat). 
* 3A_code: The 3 letter code used for aquatic species in FishStatJ. (Therefore, only aquatic). 
* description: More details on each item, mainly latin names of species but also additional information.

nutrient_production.csv

This file contains the following columns

* UN_CODE: Country code following the UN (M49) system. 
* FAO_code: Country code following the FAOSTAT system. 
* year: Year of production data
* prod_source: One of four production sources; agriculture, livestock, aquaculture and fisheries
* unique_id: A unique ID number, this is unique for each species (or lowest taxonomic group where data is available).
* nut_ID: A unique ID for nutritional composition.
* prod_sum_kcal: Summed production for that ID, in that prod_source, country and year. In kcal. 
* prod_sum_protein_g: Summed production in grams of protein. 
* prod_sum_fat_g: Summed production in grams of fat. 
* prod_sum_carb_g: Summed production in grams of carbohydrates. 
* prod_sum_vitA_mcg_RAE: Summed production in micrograms of vitamin A (retinol activity equivalents: RAE)
* prod_sum_folate_mcg: Summed production in micrograms of folate. 
* prod_sum_iron_mg: Summed production in milligrams of iron. 
* prod_sum_zinc_mg: Summed production in milligrams of zinc. 
* prod_sum_calcium_mg: Summed production in milligrams of calcium. 
* fruitveg_sum_100g: Summed production of fruit and vegetable items (therefore many items 0) in 100 g. 
* Area: Country name
* pop_total: Population for that country in that year. 
The rest of the columns are as above but divided by population and 365 to get per cap per day values.
